The cleaning unit is integrally coupled to the connecting base by a latch element. The rotating unit includes a rotating base having a guide rail installed thereon, a rotating shaft integrally coupled with the rotating base, a position limit body slidably moved on the guide rail, an elastic element abutted against the position limit body, and a compressing element, for compressing the elastic element to increase a friction between the position limit body and the guide rail. The invention can achieve quick rotating, positioning, installing and uninstalling effects.

FIELD OF THE INVENTION

The present invention relates to a mop structure, in particular to a mopstructure with quick rotating, positioning, installing and uninstallingeffects.

BACKGROUND OF THE INVENTION

As a mop has become an indispensable daily product for cleaning theenvironment of a family or a public place, almost every family or apublic place has at least one mop. In a general mop comprised of ahandle bar and water absorbent cloth or cotton, the water absorbentcloth or cotton are fixed and cannot be removed easily, and the mopcannot be turned easily for the dewatering purpose, and thus such moptakes more laborious effort for its use, and requires rinsing the handlebar together while rinsing the mop.

In view of the aforementioned shortcomings of the prior art, theinventor of the present invention based on years of experience in therelated industry to conduct extensive researches and experiments, andfinally developed an improved mop structure with a simple design toachieve the quick rotating, positioning, installing and uninstallingeffects.

SUMMARY OF THE INVENTION

Therefore, it is a primary objective of the present invention to providean improved mop structure to achieve the quick rotating, positioning,installing and uninstalling effects.

To achieve the foregoing objective, the present invention discloses animproved mop structure, comprising: a mop stick, a connecting base, arotating unit installed between the mop stick and the connecting base,and a cleaning unit installed at the bottom of the connecting base. Thecleaning unit is integrally coupled to the connecting base by a latchelement. The rotating unit includes a rotating base having a guide railinstalled thereon, a rotating shaft integrally coupled with the rotatingbase, a position limit body slidably moved on the guide rail, an elasticelement abutted against the position limit body, and a compressingelement, for compressing the elastic element to increase a frictionbetween the position limit body and the guide rail. The invention canachieve the quick rotating, positioning, installing and uninstallingeffects.

To make it easier for the examiner to understand the objects,characteristics and effects of this invention, we use a preferredembodiment together with the attached drawings for the detaileddescription of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Other features and advantages of the present invention will becomeapparent in the following detailed description of the preferredembodiment with reference to the accompanying drawings.

With reference to FIG. 5 for a perspective view of the presentinvention, a mop 10 of the invention comprises a mop stick 11, aconnecting base 13, a rotating unit 12 installed between the mop stick11 and the connecting base 13, and a cleaning unit 14 installed at thebottom of the connecting base 13. Since the heights of users aredifferent, the mop stick 11 is designed as a contractible stick to copewith the heights of different users. In addition, the rotating unit 12is rotated to provide a change of angle of the mop stick 11 with respectto the connecting base 13. Such arrangement not only allows users to usethe mop 10 for mopping different floor positions (such as the positionbelow a chair), but also provides an effort-saving way of mopping afloor. The cleaning unit 14 and the connecting base 13 can be installedand uninstalled quickly. After the cleaning unit 14 picks dust or dirtup to a certain quantity, it is necessary to clean the cleaning unit 13by removing the cleaning unit 13 directly, and rinsing the cleaning unit13 in a sink, without the need of carrying a bucket of water with themop stick 11. Obviously, the mop structure of the invention is veryconvenient and practical.

With reference to FIG. 1 for an exploded view of a partial structure ofthe present invention, the rotating unit 12 comprises a rotating base121, a rotating shaft 122, a position limit body 125, an elastic element124 and a compressing element 123. The rotating base 121 includes aguide rail 1211 disposed thereon for sliding the position limit body125. The rotating shaft 122 includes a connecting slot 126 disposed atthe bottom of the rotating shaft 122 for integrally coupling therotating base 121 by a fixing element 127. The elastic element 124 isabutted against the position limit body 125, and the compressing element123 compresses the elastic element 124, such that the position limitbody 125 is pressed more closely at the guide rail 1211 to increase afriction between the position limit body 125 and the guide rail 1211. Inaddition, the position limit body 125 is a ball bearing.

With reference to FIG. 2 for an exploded view of another partialstructure of the present invention, the connecting base 13 is comprisedof a primary base 131 and a secondary base 132, and a locking element133 is provided for securing the primary base 131, the secondary base132 and the rotating unit 12 integrally as a whole. The secondary base132 includes a plurality of positioning groove holes 1321 disposedthereon.

With reference to FIGS. 3A and 3B for schematic views of an operation ofthe present invention, the cleaning unit 14 of the invention iscomprised of a plurality of cleaning bodies 141, such that when the mopis assembled, each cleaning body 141 is passed through a latch element134 and fixed onto the latch element 134, and then each latch element134 of the cleaning body 141 is latched into each correspondingpositioning groove hole 1321 of the secondary base 132 for performing acleaning operation. If the cleaning unit 14 has picked dust or dirt upto a certain quantity and it is necessary to clean the cleaning unit 14,users can apply a force to separate the latch element 134 from thepositioning groove hole 1321, so as to achieve the quick installing,uninstalling and cleaning effects.

With reference to FIGS. 4A and 4B for schematic views of anotheroperation of the present invention, a user can step on the connectingbase 13 with a foot and turn the mop stick 11, if the user wants to usethe mop 10 to clean the positions under a chair or a table. Withreference to FIG. 1 together, a force is exerted onto the position limitbody 125 in the rotating unit 12 to slide the position limit body 125 inthe guide rail 1211 of the rotating base 121, and the included anglebetween the connecting base 13 and the mop stick 11 is changed tofacilitate users to clean different position of a floor. After theincluded angle is confirmed, the position limit body 125 will becompressed by the elastic element 124 and abutted against the guide rail1211. Since the user has not applied a rotating force, therefore theincluded angle between the connecting base 13 and the mop stick 11 isfixed by the friction between the guide rail 1211 and the position limitbody 125. Obviously, the present invention is very convenient andpractical.

In summation of the description above, the present invention provides afeasible design and complies with patent application requirements, andthus is duly filed for patent application.
